PECULARITIES OF THE SOUND FIELD SPATIAL INTERFERENCE STRUCTURE IN SHALLOW WATER

摘要

Carried out theoretical researches and computer calculations let to conclude that a phenomena of sound field interference structure reforming may be observed in shallow water by analogy with the deep sea. This reforming brings about diffraction focusing of sound field. Extent and maximal distance of this effect's manifestation depend mainly on the channel eigen modes excitation behavior, depending, in turn, on location depth and directivity diagram of the sound source.
